"It went right into the stands and hit the lady almost I think right in the face cause immediately after she got hit, you see her just put her hands up in her face. And it was the longest delay, forever. You had all kinds of emergency personnel come down. It was pretty scary," Tim Reph said.

"He took a big huge swing and let the bat fly and it was twirling like that and unfortunately it hit her right in the forehead," another fan told FOX 5.

Sanchez watched from the field with a very concerned look on his face. But then he asked for his bat back, which drew booing from the stands. He gave the woman another bat to take home.

"I feel really, really bad about it, especially when I see it hit the lady. I hope she's well and they take care of her," Sanchez said.

Fortunately, the woman was able to walk out of the stadium, with her head bandaged.

"You come to a ballgame to enjoy it and when something like that happens, it's disheartening," said Padres manager Andy Green. "I think everyone hurts for her family and we're hopeful she's doing fine."

“We never want to see anybody injured while enjoying a game at Petco Park. The guests who were struck by Hector Sanchez’s bat in the 9th inning have received medical attention and been transported to a local hospital. Both were in good spirits and their injuries do not appear to be serious.

For the privacy of the guests, we cannot offer any further information.

Last season, we extended our backstop netting in accordance with Major League Baseball’s recommendations. Any injury at the ballpark warrants evaluation and discussion of current practices.”

The game went into extra innings. The Rockies beat the Padres 3-2 in the 11th.

A reporter for the San Diego Union-Tribune posted a picture on Twitter of another fan being led out of the stadium moments after the woman walked off. Kirk Kenney said the fan was arrested and ejected after refusing to move out of the area to allow a cleanup crew to access the seats.
